The AdWords Bid Simulator tool now offers conversion estimates in addition to impressions and clicks to show how bid changes may affect conversion volume and values.
For each bid option shown in the simulator, the bid simulator provides the number of conversions — both 1-per click and many-per-click — and conversion values if assigned or set. Conversion estimates show how many clicks might result in a conversion within one day, and the estimates are based on “a recent 7 day period”. (Notice Google here does not say the most recent 7 days.) Because the bid simulator is based on a seven day window, conversions that occur outside that period but still within the 30 day conversion window aren’t reflected in the estimates.
